ism acting on the paper roller or platen, in which mechanism several tooth intervals of the ratchet Wheel preferably deiine the line interval or spacing. NOW in order that it may also bepossible to adjust the roller without employing this line s acing device and merely by rotating the roliier in either direction, meansis provided by which the locking,

of the paper roller by the locking pawl of the spacing mechanism may be discontinued. In the known arrangements this means -for discontinuingthe locking is independent of the'lever-of the spacing mechanism provided With operatingpawl. This independence is prejudicial in various respects.

may readily be overlooked Whether the lockirlilg pawl is -disengaged or not. Then when the locking me spacing device 4is again used the paper is not -fed exactly, owing to the Idisengagement of the locking pawl, by the free travel othe roller and by the friction of the operating paWl upon the teeth of,` the ratchet Wheel an acceleration or retardation of the paper roller may take place, es ecially When thewriter does not completely Iiinish the necessary stroke of the operating pawl. Then pawl controls the spacing so' that when for instance theoperating paWl isonly moved the length of two` and a half teeth, the last part ofthe feed is carried out at an interval of half a tooth by the spring action ofthe locking paWl. i v

thatin which it is moved for line spacing. Owing to this arrangement many advantages which are of great lmportance `in the use of the machine are obtained. The line spacing 'mechanismffmay be. constructed in such a manner that it shows directly whether the by the position of the operating lever. In addition to this, when the writer againbegins to manipulate the spacing mechanism the locking mechanism is again engaged after the setting of the roller spacing. The novel device also renders it possible that after the adjustment of the sheet of paper for writing on separate predetermined or marked lines, the subsequent ployment in the usual manner of the line spacing device for equal line spacing. This is important, when for example only one line of the sheet is marked and from this line the Writing is to be continued with the line spacing for Which the spacing mechanism has been set. y l y `In the accompanying drawing a construe* tional form of the novel device for disengagino' the line spacer is illustrated.

cigure l represents the device in front elevation in its inoperative position. Fig. 2 shows the device in front elevation in operative position. Fig. 3 shows the device with the locking mechanism disengaged. represents it in the operative position. In Fig. 2-4 the device is in section on the line A--A of Fig. 5. Fig. is a side elevation of the device. Fig/6 is a longitiidipal section through the paper roller.

Upon the shaft ov which engagesdn the paper roller and is mounted in the `roller upright c, is arranged the operating ratchet wheel d, with which the o era'ting pawl e and the locking roller f of thell) are able to engage. By ating lever o from its position of repose the operating pawl e is pressed by the spring. 7c 'against the ratchet wheel d, -whereby the paper roller is rotated. Upon the return of the operating lever g the locking roller j', which with its arm or 'carrier Zrocks around 5 the pin m, is pressed b the springs 7i and 'i l into the tooth interval ying next to it, when the locking mechanism is not disengaged. Disengagement is effected by bringing the writing may take place directly with the em` locking device is released or not,for example 6o ihr a definite line Fig. 4 85 ocking mechanism 9 5 nose fn, on the arm carryingthe locking rollerl rigidlj,T connected with 'the rolleriipright c.

This ldisplacement of the operating lever g toward the stop, j is effected by overcoming the friction, produced hy the spring Zr', .ofthe operating pawl e against the linger p and also the influence oip the spring 'i and the'friction between'the two noses n and 0. operating .lever g bears against'the stop g, the paper roller may he rot-'ated lin'V either direction desired by means of the linnrled wheel lI'. li the operating lever g is again displaced in the spacingA direction, the locking mechanism together with -tlie loc-king roller ,1' is again released opting ,toi the' fact that the nose n comes into the .ath ofthe nosel o, so that by the influence o 1'the springs h and i the locking rolleris pressed `into the tooth interval -oiv the operating Wheel' when presented. v f I In the middle inoperative position ot' the line spacing lever g the operating paWlje is situated on the lpoint of the disengaging member p. Solong as the line spacing mechanism .is used in the ordinary manner for line spacing, tlie lever g only moves back as far as the point of the disengaged member p after the spacing has "been effected. The lever g is caused to remainin this position owing to the fact that the nose 0 bears against the nosen of the locking mechanism Z submitted to theviniluence of' the spring h. The spring Zz.. retains the locking mechanism f, Z with the -nose/nl in` its place so strongly that the spring i is not able to overcome the resistance of the first spring Zi. Only after a comparatively powerful pressure upon the lever g, whereby this latter is moved from its position in Fig. 2 to that shown in Fig. 3, is it possible to press oacli the locking mechanism j, Z,

so that the lockingr rollerj' comes ont of engageinent with the locking wheel d. Then -this latter may be rotated freely in both directions by means ofA the knurled wheel 7 (Fig. 1. 5, 6) independently of the locking mechanism, so that the roller and the sheet ol paper may be readily adjusted as desired.

A, The lever g remains in the yposition indicated in Fig. 3 under the iiiuence offthe spring i, T he spring Zt is able to reiiitrce". the action of the spring 'i in this position owing to the fact that the nose n is pressed against the back of the locking tooth o. It it is desired to again use the devine for line spacing, the lever f/ is again pressed forward in the feed direction as shown in Fig. At the moiviien mais to be done- Whenthe again releases the operating pa'wl e `the lockmg- Amechanism f, Z is again lengaged.
